To an whom it may wacaa- Be it known that I, Oliiin Wastes, a subj'e ct of the King of Sweden, and resident of Chicagb, county of Coio'k, and State 'of Illinois, have invented certain new aiid useful Improve eiits in Adjustable I-Iaiigers, of which the folldwing is a sp'tifitatica;

My iiiveiition relates to adjustable shaft hangers, and has for its object improvements in said devices; t

In the accompanying drawings 1 Fig. 1 is 'a side elevation of a hanger for a countershaft; H y c} .Fig. 2 is ah elevation in the direction 2 F s- Fig. 3 is a longitudinal sctioh at the Bearing and a part of the hanger frame;

a is a section on line of Fig. 3; I 5 is a side elevation of a modified forinof haiiger; aiid Fig. 6 is a front elevates of the saint.

The frame 11 is providedwith feet 12 by which it is secured in place in the or inary manner. The frame 11 is provided with an inclined slot 13, the width of which is a trifle more than the outside diameter of the bearing 14; carried by the hanger. At the upper side (if this slot the frame a tongue 15 which projects into a groove in the bearing as shown in Figs. 1, 3 and 4. This tongue terminates at a point 16 so that when the bearing is moved upward in the slot to its highest point it may be withdrawn laterally from the hanger.

The part 17 of the frame 11 which is below the slot 13, is slotted in a plane perpendicular to that of slot 13, and in this last named slot is a ratchet bar 18 pivoted at 19 to the frame. A spring 20 connected be tween pin 21 on the frame and pin 22 on the ratchet bar serves to hold said bar normally in theposition shown in full lines in Fig. 1. A cord or rod 23 provided with a handle 24 serves as a means for moving the bar 18 to the dotted line position.

The central part of the bearing 14, which is opposite the groove arranged to receive the tongue 15, is provided with teeth 25 which match the teeth on the bar 18. This side of the bearing is flat and bears against the part 17 so as to restrain the bearing from turning on its axis.

WVhen the bearing is in the position shown in Fig. 1, it may be pushed upward by hand in the slot 13. In a case of this kind, the

s rin 20 ields to ermit such u Ward P e y P P movement and acts tot-hold the ratchet bar as as to prevent a downward movement. By pulling oaths beta 25. however, the ratchet bar is freed item the ratchet teeth on at bearing and said bearing-,slides dowiiw'ai'd slot 13 by gravity or b lt pull.

On thefshaft 26 are the-'ordirlary pulleys 27 The belt 28 extends from the; couiitershaft tothe main drive shaft, and belt 29 extends to the machine to be driven; It will be evident that moving the 'shaft 26 upward along the incline represented 'by slot 13 serves to tighten both belts at thelsame time. are attheir lowest p'ositioh when the belts 28 and 29 a're firstput 'omadjustments upward of the shaft will serve to take up slack ftir iiite a while before' it is necessary to tighten the belts by cutting out a piece and relacing them. And when it does become necessary to shorten the belts, theshaft may be dropped to its lowest position, and long pieces ofbelt may be taken out instead of short pieces. I I

p Also, if an accident occurs at the machine bingdriven, that machine may be instantly stoppedv by. pulling the cord 23 and permitting the shaft 26 to move to its lowest position. In such a ease, the gravity of the shaft and pulleys is assisted by the pull of the belts 28 and 29.

On each bearing is an arm 30 secured in place by a set screw 31. On the outer ends of such arms is carried by the ordinary belt shifter 32.

In the form shown in Fig. 5, the frame 11 is not in one piece with the feet 12, but said feet are on a bracket 33 having thereon a hub 34. On the frame 11 is another bracket 35 having a corresponding hub 36. A bolt 37 passing through both hubs and provided with a nut 38 serves to secure the two hubs together, and consequently the frame 11 to the feet 12. The faces of the hub where they cometogether are provided with teeth 39 so that when the nut 38 is tightened there is no tendency for the frame 11 to slip'with respect to the bracket 33.

In Fig. 1 the line of adjustability of the If the bearings 6f the countersliaft may be made more or less as, desired. The essential difference between Fig. 1 and Fig. 5 is that one of them has a fixed line of ad justability whereas thevother has a variable line of adjustability. By shifting the'line of adjustability from 45 degrees to some other angle, a given amount of adjustment will tighten one belt "more than the other.

WVhat I claim is: I v 1. A hanger having an inclined slot there. in and a second slot perpendicular to the first slot, a bearing located in the firstslot and movable longitudinally therein, said bearing having teeth adjacent to the second slot, and a ratchet bar pivoted inthe second slot and engaging the teeth of the bearing.

,2. A hanger having two slots therein perpendicular to each other, a bearing adjustably supported in one of said'slots, and a pivoted bar located in the other of said slots and serving to retain said bearing at any desired adjustment.

3. Abearing, a hanger having an inclined slot therein, said slot being so arranged that the bearing may be inserted therein at the upper end thereof and then be moved downward therein, an interlocking connection between hanger and bearing so arranged as to prevent the displacement of the hearing from the slot at any "other position than at'the upper end of said slot, and releasable holding devices arranged to retain the hearing at any intermediate position in saidslot.

' 4. A hanger having an inclined slot therein, a bearing in said slot and under strain to move downward therein,said bearing having teeth on the side which engages the hanger at the lower side of the slot, a ratchet bar located within the body of the hanger and engaging the teeth on the bearing, and amanually operated device for releasing said bar from said teeth.

5. A hanger'having a slot therein, a bearing arranged to slide in said slot and having a series of teeth on one side, a bar secured to the hanger and having a longer series of teeth than the series on the bearing, a spring acting to hold the teeth of the bar in engagement with the teeth of the bearing, and a manually operated connection for releasing the bar from the bearing, said parts being so constructed that at any position of the bearing a series of teethon the bearing engages a series of teeth on the bar.

6. A hanger having an inclined slot, a bearing located in said slot and under strain to move downward therein, a ratchet device pivoted to the hanger, a spring acting upon the ratchet device to cause it to restrain the downward movement of the bearing, and a connection for releasing the ratchet device.

7. A hearing having a groove on one side and ratchet teeth onthe other, a hanger having an inclined slot arranged to receive the bearing and the hanger having a tongue projecting into the groove to prevent the displacement of the bearing, a ratchet bar pivo-ted tothe hanger, a spring acting to press the teeth of the bar into engagement with the teeth of the bearing, said parts being so arranged as to restrain the downward movement of the bearing but to permit its upward movement under pressure, and a connection for releasing the bar so as to permit a downward movement of thebearing.
